General industrial ultrasonic cleaning machine cleaning including vehicles, ships, aircraft surface cleaning, generally can only remove the relatively coarse dirt; Precision industrial ultrasonic cleaning machine cleaning includes the cleaning of various products in the process of processing and production, the cleaning of various materials and equipment surfaces, etc., which is characterized by the removal of small dirt particles; Ultra-precision ultrasonic cleaning machine cleaning includes ultra-precision cleaning of mechanical parts, electronic components, optical components, etc., in the precision industrial production process, in order to remove extremely small dirt particles.
According to the different cleaning methods of ultrasonic cleaning machine, it can also be divided into physical ultrasonic cleaning machine cleaning and chemical ultrasonic cleaning machine cleaning: using the principles of mechanics, acoustics, optics, electricity, heat, relying on the role of external energy, such as mechanical friction, ultrasonic, negative pressure, high pressure impact. Ultraviolet light, steam and other methods to remove dirt on the surface of objects are called physical cleaning; Relying on the action of chemical reactions, the use of chemicals or other solvents to remove dirt on the surface of objects is called chemical cleaning. For example, use various inorganic or organic acids to remove rust and scale on the surface of objects, use oxidizers to remove stains on the surface of objects, use fungicides, disinfectants to kill microorganisms and remove mildew. Physical cleaning and chemical cleaning have their own advantages and disadvantages, and have a good complementarity. In the actual application process, the two are usually combined to obtain a better cleaning effect of the ultrasonic cleaning machine.
According to the different cleaning media of ultrasonic cleaning machine, it can be divided into wet cleaning and dry cleaning: Generally, the cleaning in the liquid medium is called wet ultrasonic cleaning machine cleaning, and the cleaning in the gas medium is called dry ultrasonic cleaning machine cleaning. Most of the traditional cleaning methods are wet cleaning, and the dry cleaning that is easier to understand is the vacuum cleaner. But in recent years, dry cleaning has developed rapidly. Such as laser cleaning, ultraviolet cleaning, plasma cleaning, dry ice cleaning, etc., in the field of high, fine, sharp industrial technology has been rapid development.
The high efficiency and high cleanliness of ultrasonic cleaning machines benefit from the penetrating and cavitation shock waves generated when the sound waves propagate in the medium. Therefore, it is easy to clean the parts with complex shape, inner cavity and fine air, and the general oil removal, rust prevention, phosphating and other processes can be completed in only two or three minutes under the action of ultrasonic wave, the speed can be increased several times to dozens of times than the traditional method, and the cleanliness can also reach a high standard. This in many cases with high requirements for product surface quality and productivity, more prominently shows that other processing methods are difficult to achieve or irreplaceable results.
Compared with the special cleaning machines, dry ice cleaning machines, steam cleaning machines, laser cleaning machines, pipeline cleaning machines, artificial immersion washing, brushing, pressure washing, vibration cleaning, jet cleaning, jet cleaning, shaking cleaning and other cleaning methods and processes that are used in many factories, ultrasonic cleaning methods have irreplaceable advantages and versatility. It is mainly reflected in the following aspects:
1) High precision: Because the ultrasonic energy can penetrate fine gaps and small holes, it can be applied to any parts or assembly cleaning. When the parts to be cleaned are precision parts or assemblies, ultrasonic cleaning often becomes the only cleaning method that can meet its special technical requirements.
2) Fast: ultrasonic cleaning is much faster than conventional cleaning methods in terms of workpiece dust removal and scaling. Assemblies can be cleaned without disassembly. The labor-saving advantages of ultrasonic cleaning often make it the most economical way to clean.

3) Consistency: No matter whether the cleaning part is large or small, simple or complex, single piece or batch or on the automatic assembly line, the use of ultrasonic cleaning can obtain unparalleled uniform cleanliness of manual cleaning.
